When removing oil drain bolt, since it is hard to apply torque at insertion angle 9.5 mm, purchase for TONE ratchet handle 371 with insertion angle of 12.7 mm. I just tried to set, but I feel that the manufacturers are exactly the same.

I purchased it because I need a 27 mm socket to adjust the tension of the street triple chain. Basically it's all in TONE's tool, so there were cheap ones, but choosing without hesitation. It is a safe brand.

I bought it to remove the fixing bolt fixing the bicycle crank. Since the bolt is in the crankshaft hole, it is necessary for the socket to have an outer diameter that can be inserted into the shaft hole. Since detailed dimensions are described in the description, it is safe to check the outside diameter. Of course the fixing bolt could be removed without problems! There is also a socket with no description of dimensions, so to avoid failures such as being thicker than the shaft hole after purchase, it is helpful to mention the detailed sizes on other sockets too. Monotaro please.

Very satisfied. I frequently use domestic first-class manufacturer products that can be used with high frequency tools frequently. With the same length as before, taking out from the socket's tool box, exchanging the socket such as the ratchet handle, etc., it is smooth and easy to handle.
